The closure is something of a blow to downtown, which has been struggling to draw high-end retailers. There has been a boom in high-end condo and loft construction over the last decade, but residents have complained about a lack of shopping opportunities.

Downtown boosters have hoped the Frank Gehry-designed Grand Avenue complex on Bunker Hill would draw more luxury retailers. But that development has been delayed because of the bad economy. Brooks Brothers tended to cater to the downtown office set.

The store will close next week. Customers will then have to go west to stores in Century City and Beverly Hills.
